Just as an aside, possibly interesting: pkgsrc (a multiplatform package building and management system, see www.pkgsrc.org) has its own way of fixing this. Each package specifies the others that it needs, and only those are made visible to configure and the compiler. Everything else is hidden (up to a point). The way it works is with shadow-directories for include and library files, which contain symlinks to the real files, for everything that the build tools are supposed to see. Wrappers around the tools translate directory names and enforce that no uncleaned paths are used. It works fairly well, unless a configure script uses very nonstandard ways to find stuff. -Olaf. -- ___ Olaf 'Rhialto' Seibert -- Wayland: Those who don't understand X \X/ rhialto/at/falu.nl -- are condemned to reinvent it.
